UNC/UNF Inch key locking inserts provide high strength and are designed to provide high resistance to rotation and pullout loads. After installation into the tapped hole, the locking keys on each keys inserts are driven down through the threads of the parent material, locking the insert firmly and permanently in place.Available in inch and metric thread sizes, the stainless steel solid bushing configuration of the Keys inserts guarantees the quality of the internal thread before installation. No special tools are required for installation and standard taps and drills are used for hole preparation. The pre-assembled self-broaching keys set the insert to depth and ensure positive resistance against rotation.
